add --redis flag

[ababino]

📝 Summary

edit bidcollect.go, bid-processor.go and bidcollector.go to accept the --redis falg

⛱ Motivation and Context

Since PR50, the default behavior of the bid collector is to assume that there's a redis service running, even if we do not add the --redis falg.

If you run:

go run . service bidcollect --data-api --ultrasound-stream --all-relays

You will get this error:

failed to create bid collector                error="dial tcp [::1]:6379: connect: connection refused"
exit status 1

A workaround is to set --redis-addr ""
